Lunyu XVII. 8. (455)

Knowledge, acquired by learning, is necessary to the completion of virtue, by preserving the mind from being beclouded.
1. The Master said, "Yû, have you heard the six words to which are attached six becloudings?" Yû replied, "I have not."
2. "Sit down, and I will tell them to you.
3. "There is the love of being benevolent without the love of learning;– the beclouding here leads to a foolish simplicity. There is the love of knowing without the love of learning;– the beclouding here leads to dissipation of mind. There is the love of being sincere without the love of learning;– the beclouding here leads to an injurious disregard of consequences. There is the love of straightforwardness without the love of learning;– the beclouding here leads to rudeness. There is the love of boldness without the love of learning;– the beclouding here leads to insubordination. There is the love of firmness without the love of learning;– the beclouding here leads to extravagant conduct."

To love trustworthiness in word without loving learning is liable to lead to harmful behaviour. To love forthrightness without loving learning is liable to lead to intolerance. To love courage without loving learning is liable to lead to insubordination. To love unbending strength without loving learning is liable to lead to indis- cipline.'
